Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Every once and a while a compile will result in dm_init() returning NRF_ERROR_INVALID_ADDR. Looking at device_manager_peripheral.c:dm_init(), it looks like this error is coming...
Has anyone experience of successful TICK_DV calibration for nRF9E5? What order of accuracy should be achievable?
In my application I maintain a software RTC clocked by...
Hi,
I want to periodically send data through nrf8001 so that once the connection is established for a particular service, i can periodically send data . So how to create...
Hi nordics!
I want to using app_data for preserving data.
For that.
First, I change the value DFU_APP_DATA_RESERVED to "0x0400"
Second, I change the memory start...
I have the "old style" nRF6310 board + nrf51422 boards.
I want to test different examples from the latest sdk, and possibly with different softdevices as well.
I appreciate...
Actually we are facing some problems debugging our custom code using breakpoints and/or single stepping.
Searching the forum I found that using the uart seems a possible...
I was doing some range testing using the ack payload feature of nRF24L01 modules, and I noticed that using different packet sizes would affect the number of packets per second...
Hi
I have a MCU with an external sensor connected via SPI sampling data at 1000Hz.
Using the nRF8001 with REQN and RDYN lines is making trouble. The REQN line is pulled...
I am trying to accomplish the following very simple task: use the broadcasting function of my nrf 8001 to send up to 19 Bytes of data over the air (connectionless).
I tried...
I need to create a backlight fade-in/out effect. For this I'm using the latest nrf_pwm lib form here together with the S110 Softdevice. Using the scheduler and an application...
Hi All,
We have been working on Arduino Mega board with BLE shield. We want to get the address of the BLE shield and we are using aci library for that.
I found this...
Hello,
Im using the master control panel app from nordic to use the DFU.
I can only once upload the application over DFU on my nRF51422. Because after the upload is...
